I can verify MS-generated signature on helloworld.exe (first test
case, built with mingw) using Mono chktrust. This means our hash
calculation is correct, at least in this case, as the code path for
signcode is a little different.

+Fixed in SVN r69502. Both cases looks similar, extra data after the
+EXE, but required different fixes.
+
+The first case has a (deprecated) COFF debug information and while the
+document is very clear that any debug data must be after the attribute
+certificates (authenticode signature) it doesn't seems to apply to
+COFF debug info (MS put the signature after the COFF stuff).
+
+FIX: COFF debug is deprecated. Mono's signcode will strip this data,
+if present, when signing (i.e. I'm not gonna include a COFF parser as
+this feature is unused anywhere else inside Mono).
+
+The Nullsoft installer EXE is different. There is extra data but it
+isn't "registered" anywhere in the headers (if falls outside all
+sections). The old code would have worked, except that the alignement
+(on 8 bytes) was bad.
+
+The good news is that this allowed me to refactor the existing code
+and fix another issue (when using a test certificate created with MS
+makecert "Root Agency").
+
+Thanks for the report, the updated documentation and the samples!
